Location: Santa Cruz Department Map
Area: 15,234 km²
Noel Kempff Mercado National Park (Parque Nacional Noel Kempff
Mercado) is one of Bolivia’s largest and most intact protected
areas, a UNESCO World Heritage Site covering roughly 1.52 million
hectares in the northeastern Santa Cruz Department along the
Brazilian border.
It protects a dramatic transition zone of
Amazon rainforest, cerrado savanna, gallery forests, wetlands, and
the ancient Huanchaca (or Caparú) Plateau, a Precambrian sandstone
mesa rising hundreds of meters above the lowlands. The plateau and
its waterfalls are widely linked to the inspiration for Arthur Conan
Doyle’s The Lost World, after explorer Percy Fawcett surveyed the
area in 1908.
Established in 1979 as Huanchaca National Park and
renamed in 1988 for the Bolivian biologist Noel Kempff Mercado
(murdered in the park while researching), it was inscribed on the
UNESCO list in 2000 for its mosaic of habitats and viable
populations of globally threatened large vertebrates.
Visitor
numbers remain low (around 1,500 annually in recent reports), which
helps preserve its wilderness character but means infrastructure is
basic and logistics are complex.
Key Highlights and What to See
The park’s signature features
include:
Huanchaca/Caparú Plateau: One of the largest protected
tracts of undisturbed cerrado. Trails climb the escarpment for
panoramic views over continuous Amazon canopy. The summit supports
distinct grassland, scrub, and gallery forest communities.
Waterfalls: Arcoíris (Rainbow) Falls (~80–88 m), where mist often
produces rainbows; Federico Ahlfeld Falls; and El Encanto Falls.
These drop from the plateau edge into the forest. Boat or hike
access varies by sector and season.
Rivers: The Iténez (Guaporé)
forms the northern/eastern border. Boat trips reveal giant river
otters, black caimans, pink river dolphins, and abundant waterbirds.
The Paraguá and Pauserna rivers offer similar opportunities.
Habitats and wildlife: Tall Amazonian forest, palm stands,
seasonally flooded savanna, and dry forest. Documented fauna
includes at least 139 mammal species, over 620 bird species, 74
reptiles, and 62 amphibians. Flagship species include jaguar, puma,
maned wolf, giant anteater, lowland tapir, marsh deer, giant
armadillo, and all major Bolivian primates. Birds feature harpy
eagle, multiple macaw species (including hyacinth), and many
endemics or restricted-range species. Reptiles include green and
yellow anacondas and large caimans. The cerrado plateau holds
distinct species from the lowlands.
Wildlife sightings are
never guaranteed but are often better than in more visited Amazon
sites due to low human pressure. Dawn and dusk walks, river trips,
and quiet observation improve chances. Early morning or late
afternoon activity peaks.
Best Time to Visit
The climate
is tropical with a pronounced dry season. Annual rainfall is roughly
1,400–1,500+ mm, concentrated in the austral summer.
Dry
season (roughly May–October, peak June–September): Best overall
window. Trails and roads are more passable, mosquitoes are fewer,
and wildlife concentrates near water. Temperatures average in the
mid-20s °C but can drop sharply (sometimes to near 10 °C or lower)
during surazos (cold fronts from Patagonia). Ideal for hiking and
logistics.
Wet season (roughly November–April): Waterfalls are
fuller and vegetation lush, but many tracks become impassable,
rivers rise, and access by road is unreliable. Some operators limit
or cancel trips.
Late dry season (September–October) often
balances good conditions, residual greenery, and slightly lower
demand. Confirm current fire risk and road/airstrip status, as
wildfires have affected parts of the park in recent years.
Getting There and Access Logistics
This is an expedition-style
destination, not a casual day trip. Independent travel is difficult;
most visitors use licensed operators who handle permits, transport,
guides, and logistics.
Primary options:
Charter or small
aircraft from Santa Cruz de la Sierra: Flights of about 1.5–2.5
hours to airstrips at Flor de Oro (northern sector, on the Iténez
River) or Los Fierros (southern sector). This is the most practical
and scenic route, offering aerial views of the forest and plateau.
Costs are high for private charters; group tours share the expense.
Overland (dry season only): From San Ignacio de Velasco (the nearest
larger town, roughly 100–200+ km depending on route) via rough
unpaved tracks. Journeys of 12–20+ hours or multi-day are common,
often requiring 4x4 and river crossings. Routes may pass Jesuit
mission towns or communities such as Florida or Piso Firme. Some
combine bus travel with boat or further 4x4.
River access:
Possible from communities like Piso Firme or Remanso by boat along
the Iténez or Paraguá, especially for the northern sector.
There is no regular public transport into the park interior.
Facilities and vehicle availability at ranger stations can vary.
Always pre-arrange entry with SERNAP (Bolivia’s National Service of
Protected Areas) or a licensed operator; drop-in visits without
prior clearance are not permitted. Ranger stations at Flor de Oro
and Los Fierros handle registration and briefings (typically daytime
hours).
Permits, Fees, and Guides
Entry requires advance
authorization. Recent sources list fees around 100 BOB (~$14–15 USD)
for foreign visitors and 30 BOB for Bolivian nationals/residents,
with children and some local community members free, though older
reports vary and proposals for higher fees (e.g., 200 BOB
foreigners) have appeared. Confirm current rates with SERNAP or your
operator, as they can change.
Licensed guides or park rangers are
effectively mandatory for entry and exploration. Guide fees are
typically bundled into tour packages or quoted separately ($80–150+
USD/day depending on group size and expertise). Operators based in
Santa Cruz (examples historically include Ruta Verde, Nick’s
Adventures, and Amboro Tours) arrange multi-day trips that include
transport, meals, basic lodging or camping, and activities.
Plan
4–7 days minimum for a meaningful visit covering key sites. Shorter
trips are possible but limit what you can see.
Accommodation
and Facilities
Options are limited and rustic:
Flor de Oro
(north): Historically the more developed base, with cabins, dining
area, solar power, and river access. Status has fluctuated; confirm
current condition.
Los Fierros (south): More basic ranger
station/camping facilities near forest trails and the plateau.
Reports of rundown infrastructure are common.
Camping is
available at designated sites. Some itineraries use community-based
lodging outside the core park or simple camps near waterfalls.
Bring or confirm that the operator supplies tents, sleeping
gear, water purification, and food. There are no shops or
restaurants inside the park. Expect solar power or none, limited
water, and basic sanitation.
Activities and Suggested Focus
Typical itineraries combine:
Boat excursions for wildlife and
waterfall approaches.
Hiking to plateau rims, waterfalls, and
forest trails (moderate fitness required; some climbs are
demanding).
Birdwatching (excellent diversity; specialists
recommend focused trips).
Night walks or vehicle surveys where
permitted.
Photography and quiet observation.
North-side
trips emphasize river systems and Ahlfeld/Arcoíris waterfalls;
south-side trips focus more on the plateau, El Encanto, and forest
trails. Combining both is ideal but logistically heavier. Insist on
Huanchaca Plateau time if it is a priority, as some itineraries
under-emphasize it.
Practical Visiting Tips
Health and
safety: Yellow fever vaccination is recommended or required for
Bolivia; consult a travel clinic about malaria prophylaxis, dengue,
and other tropical diseases. Use strong insect repellent (DEET or
equivalent), long sleeves/pants (especially at dawn/dusk), mosquito
nets, and treat clothing. Carry a basic first-aid kit, any personal
medications, and water purification. Watch for caimans, snakes, and
insects. The area has reported illicit activity (including past
drug-related issues and occasional illegal airstrips), so travel
only with reputable operators and follow all ranger guidance. Do not
wander alone.
Packing: Lightweight, quick-dry clothing in neutral
colors; sturdy waterproof hiking boots; rain jacket and pants; sun
protection (hat, sunglasses, high-SPF sunscreen—open cerrado offers
little shade); headlamp/flashlight with spare batteries; binoculars;
camera with extra batteries/memory; personal toiletries and
biodegradable soap; cash (cards rarely work); copies of documents.
Layers for temperature swings. Waterproof bags for gear.
Budget:
Beyond park fees, the main costs are transport (especially flights
or private 4x4), guides, and all-inclusive tour packages. Multi-day
guided trips historically ran several hundred dollars per person
(shared groups are cheaper). Food and basic lodging are usually
included. Factor in contingency for weather delays.
Sustainability and rules: Stick to trails, maintain distance from
wildlife, pack out all trash, and follow no-trace principles.
Fishing is typically catch-and-release where allowed. Photography is
generally fine; avoid drones unless explicitly permitted. Support
local communities and licensed operators.
Preparation: Book well
in advance. Check current conditions (fires, roads, airstrips,
security) with SERNAP and your operator close to departure. Physical
fitness helps for trails and heat/humidity. Spanish is useful;
English-speaking guides are available on many organized trips.
Nearby context: San Ignacio de Velasco is a useful staging point.
Jesuit mission towns en route offer cultural stops. The park borders
Brazilian protected areas, but cross-border logistics are not
straightforward for most visitors.
Location and Boundaries
The park lies primarily in the
northeastern Santa Cruz Department (Velasco / José Miguel de Velasco
Province, municipality of San Ignacio de Velasco), with a smaller
portion extending into the Beni Department (Iténez Province,
municipality of Baures). It runs parallel to the Brazilian border,
adjoining the states of Mato Grosso and Rondônia. The Iténez (Guaporé)
River forms much of its eastern and northern boundary with Brazil; it
also borders Brazil’s Serra Ricardo Franco State Park.
Coordinates
span approximately 13°32′–15°06′S and 60°13′–61°50′W, with a central
reference near 14°16′S, 60°52′W. It sits roughly 430–700 km northeast of
Santa Cruz de la Sierra; San Ignacio de Velasco is the nearest
significant town. The park is part of the Brazilian Shield and the
broader Amazon drainage system.
Altitude and Major Landforms
Elevation ranges from about 200 m in the lowlands to nearly 980–1,000 m
on the plateau summits.
The dominant feature is the Huanchaca Plateau
(Meseta de Huanchaca, also called Caparú or Caparuch Meseta, or Serranía
de Huanchaca). This is a large, flat-topped Precambrian sandstone and
quartzite mesa roughly 150 km long and 45–50 km wide, covering several
thousand square kilometers (total tableland area around 6,800–7,000 km²,
mostly in Bolivia). Its sheer cliffs rise 200–700 m above the
surrounding Amazonian lowlands, creating dramatic escarpments.
These
ancient rocks date to more than a billion years ago (Proterozoic /
Precambrian Brazilian Shield), with later Cretaceous sandstones,
laterites, and duricrusts on the surface. The plateau’s isolation and
nutrient-poor, well-drained soils support distinctive cerrado
ecosystems. Explorer Percy Fawcett surveyed the area in 1908; his photos
of the mesa are widely credited as the inspiration for Arthur Conan
Doyle’s novel The Lost World.
Surrounding the plateau are piedmont
slopes, river valleys, and extensive alluvial plains of the Precambrian
lowlands.
Hydrology
The park drains into the Amazon via the
Iténez (Guaporé) River basin—one of the Amazon’s richer tributaries. Key
rivers include:
The Iténez/Guaporé itself (eastern/northern
border).
Verde River (also partly a border river).
Paucerna and
Paraguá rivers (and their tributaries).
Several rivers originate
on the Huanchaca Plateau and plunge off the escarpment as spectacular
waterfalls, including Arcoíris (Arco Iris, ~80–88 m), Federico Ahlfeld
(25–45 m), El Encanto (~80 m), and others such as Fawcett. There are
also fluvial and tectonic lakes, lagoons, seasonally flooded savannas,
várzea (flooded) forests, and wetland systems. Rivers form roughly 90%
of the park’s long border.
Climate
The climate is tropical,
warm, and humid, with a distinct dry season. Mean annual precipitation
is typically 1,500–2,000 mm (locally higher, up to ~2,500 mm in places).
Most rain falls in the austral summer; the dry season (roughly
June–September) sees less than 30 mm per month. Mean annual temperatures
are around 25–26 °C (77–79 °F). Cold fronts (surazos) from the south can
briefly drop temperatures to about 10 °C (50 °F).
Ecosystems and
Biogeographic Setting
The park sits at a major ecological transition
where Amazonian rainforest, cerrado (Brazilian-style savanna and dry
woodland), and elements of Chiquitano dry forest meet. This produces an
exceptional mosaic of habitats over a modest elevational range:
Upland evergreen Amazonian forests (tall rainforest with emergents such
as Brazil nut, mahogany, and ceiba in northern and western lowlands).
Semi-deciduous and deciduous dry forests in transition zones.
Extensive cerrado savanna and grassland, especially the isolated tracts
on the Huanchaca Plateau (among the largest protected undisturbed
cerrado areas).
Gallery/riparian forests along rivers.
Palm
forests, flooded savannas, wetlands, swamps, and várzea forests.
The plateau’s cerrado has been geographically isolated for millions of
years, functioning as a natural laboratory for evolutionary processes.
Lowland soils are deeper and more fertile in places, supporting denser
forest, while thin soils on weathered sandstone favor open savanna.
Three ecoregions converge here: southwestern Amazonia, cerrado, and
small islands of Chiquitano dry forest.
Ecosystems and Flora
The park contains a rich mosaic of habitats:
tall evergreen (humid Amazonian) rainforest, gallery forest,
semi-deciduous and deciduous tropical forests, liana-dominated forests,
Attalea phalerata-dominated palm brakes, flooded forests, termite
plains, flooded savannas, muddy plains with forest islands, palm swamps,
and upland Cerrado dry forests/savannas on the plateau.It is estimated
to hold approximately 4,000 species of vascular plants, of which about
2,705 have been identified (with more under evaluation). Rough
distribution of identified species includes roughly 1,500 in moist
forest, 800 in Cerrado, 700 in dry forest, 500 in savanna wetlands, and
500 in aquatic, disturbed, or rock-outcrop habitats. The most diverse
family overall is Fabaceae (legumes), present across nearly all
ecosystems and life forms except epiphytes. Other widespread families
include Rubiaceae, Melastomataceae, Bignoniaceae, and Apocynaceae.
Habitat specialists include grasses and related families
(Gramineae/Poaceae, Cyperaceae, etc.) in Cerrado and certain wetland
families (Lythraceae, Xyridaceae, etc.) in savanna wetlands. About 110
orchid species have been recorded.
Key vegetation types and
features:
Humid evergreen rainforests (especially northern and
western lowlands and deeper soils): Tall forests with emergents
exceeding 45 m, including valuable timber species such as mahogany
(Swietenia macrophylla, “mara”), Spanish cedar (Cedrela odorata), and
others, plus ceiba and Brazil-nut relatives. These are floristically
distinct from western Amazon and Andean piedmont forests and are the
most species-rich formation locally, though overall diversity and
endemism are moderate compared with some other Neotropical rainforests.
Liana forests and transitional dwarf forests also occur.
Cerrado on
the Huanchaca Plateau: Fire-adapted, open to scrubby savanna on
nutrient-poor, well-drained soils. Isolated for millions of years, it
functions as a living laboratory for ecosystem evolution and holds
species once thought restricted to central Brazil, plus Bolivian
endemics and restricted-range plants. Characteristic twisted trees with
thick bark, grasses, and shrubs. Subtypes include campo sujo, campo
limpo, and cerradão.
Dry and semi-deciduous forests: Pockets
resembling Chiquitano dry forest (similar to formations in Paraguay,
Argentina, and Brazilian Caatinga), with species such as Amburana
cearensis (“roble”).
Wetlands and floodplains: Seasonally flooded
savannas, termite plains (thousands of mounds), palm swamps dominated by
Mauritia flexuosa (buriti, source of fruit oil) and Mauritiella, gallery
forests, and forest islands. Slight topographic changes drive sharp
vegetation shifts.
Notable plants include various palms (Attalea spp.
including A. phalerata and A. maripa, Mauritia flexuosa, Socratea
exorrhiza, Euterpe precatoria/açaí, Bactris spp., Acrocomia, etc.),
bromeliads, heliconias, arums, passionflowers, rubber (Hevea
brasiliensis), and orchids. Economically or culturally important trees
include mahogany, cedar, and rubber. Recent botanical work has
documented new species (e.g., Poteranthera inopinata, Melastomataceae,
in humid/seasonally flooded savannas in 2023) and numerous endemics or
threatened plants on the plateau (e.g., restricted Bolivian endemics
such as certain Euphorbia, Passovia, Myrcia, and Bromelia species). The
plateau and transition zones support high levels of plant endemism and
threatened taxa.Paleoecological records show that much of the area was
savanna and seasonally dry forest during the last glacial period; humid
evergreen rainforest expanded more recently (especially in the last
~2,000–3,000 years) with changing climate and fire regimes.
Fauna
Habitat diversity supports exceptional animal diversity and viable
populations of many large, globally threatened vertebrates. Documented
figures (approximate and subject to ongoing surveys) include at least
139 mammal species, ~620 bird species (roughly 20% of South American
birds; higher counts exist when migrants are included), ~74 reptiles,
~62 amphibians, and ~250 fish species. Insects are also highly diverse
(e.g., 97 dung-beetle species recorded in one survey—one of the highest
for the Neotropics in an area of this size).
Mammals: Most species
occur in humid forests (over 80% of records). Flagship and notable
species include:
Carnivores: Jaguar (Panthera onca, including
black jaguars), puma, ocelot, bush dog (Speothos venaticus), giant otter
(Pteronura brasiliensis, Endangered; along rivers such as the Verde and
Paucerna), long-tailed otter.
Ungulates and others: Lowland tapir
(Tapirus terrestris), brocket deer (Mazama spp.), marsh deer
(Blastocerus dichotomus), pampas deer (Ozotoceros bezoarticus—notable
populations on the southern plateau), collared and white-lipped
peccaries, capybara.
Primates: White-bellied/spider monkeys (Ateles
belzebuth), red howler monkeys (Alouatta seniculus), Geoffroy’s monk
saki, marmosets, and essentially all Bolivian primate species in some
accounts.
Others: Giant anteater (Myrmecophaga tridactyla), giant
armadillo (Priodontes maximus), maned wolf (Chrysocyon brachyurus in
open/termite savannas), Amazon river dolphin/boto (Inia geoffrensis in
the Iténez/Guaporé River).
The park protects significant
populations of many threatened large mammals and is an important refuge
for several rare Bolivian species.
Birds: Extremely diverse, with
peak richness in humid forests. Highlights include:
Parrots: Nine
macaw species (including the hyacinth macaw Anodorhynchus hyacinthinus,
Endangered/Vulnerable, in river valleys and palm areas) and about 20
parrot species.
Raptors: Harpy eagle (Harpia harpyja), king vulture.
Others: Jabiru stork, greater rhea, red-throated piping-guan, Gould’s
toucanet, various manakins, and many Cerrado specialists (e.g.,
black-and-tawny seedeater Sporophila nigrorufa, rufous-sided
pygmy-tyrant). The park is important for range-restricted or
near-threatened Amazonian and Cerrado birds, including the only
protected-area population of the rusty-necked piculet in seasonally
flooded forests along the Iténez.
Reptiles and amphibians: Green
anaconda (Eunectes murinus), yellow anaconda, black caiman (Melanosuchus
niger), yacare/spectacled caiman, yellow-spotted river turtle and giant
South American river turtle (Podocnemis unifilis and P. expansa),
red-footed and other tortoises, tegus, and various snakes and lizards.
Amphibians include leaf-litter toads, tree frogs, and others; roughly
half the herpetofauna is Amazonian, with southern/eastern elements also
present.
Fish and aquatic life: The clear-water rivers
(Iténez/Guaporé system and tributaries) and floodplains support rich
ichthyofauna and associated species such as river dolphins, giant
otters, caimans, and turtles.
